Hi all, I have recently installed 9.0-RC1 on my Thinkpad X201 and have noticed severe (~20 mins) latency to get to the third stage bootloader (/boot/loader). This is system triple booted with Windows 7 and Arch Linux using the GRUB 2 bootmanager. FreeBSD is not on a extended partition, if it matters. I have tested two BIOS disk configurations, one with AHCI and the other with IDE compatibility mode. IDE mode is comparatively faster, but still slower than expected (~3 mins). To see if this was a regression, I installed 8.2, and it has the same exact effect. Booting off of USB stick loads fine (e.g. the installer). The following is my notes with the different BIOS configurations with a link to the verbose dmesgs for each... With AHCI enabled: o dmesg output: http://dl.dropbox.com/u/45307545/dmesg_logs/dmesg_ahci.log o Timeline: ~05 mins - Loading /boot/default/loader.conf appears. ~16 mins - /boot/kernel/kernel <args> displayed. ~20 mins - Welcome to FreeBSD boot prompt. With IDE compatibility enabled: o dmesg output: http://dl.dropbox.com/u/45307545/dmesg_logs/dmesg_ide.log o Timeline: ~02 mins - Loading /boot/default/loader.conf and /boot/kernel/kernel <args> is displayed at once. ~03 mins - Welcome to FreeBSD boot prompt is displayed. After the boot prompt, startup is normal with no slowdowns to the login prompt. --- Current BIOS and ECP versions (output from Linux): --- # dmidecode -s bios-version 6QET52WW (1.22) # dmidecode -t 11 # dmidecode 2.11 SMBIOS 2.6 present. Handle 0x0027, DMI type 11, 5 bytes OEM Strings String 1: IBM ThinkPad Embedded Controller -[6QHT30WW-1.11 ]- --- FreeBSD GRUB2 entry: --- menuentry "FreeBSD 9.0-RC1" { insmod ufs2 set root=(hd0,3) chainloader +1 } Any guidance to determine the slow down of this loading problem would be great. Thank you for your time... Cheers, -John Kuczewski
